SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2007-13-08, Amendment 39-15112 (72 FR 33877, 
June 20, 2007) (``AD 2007-13-08''). AD 2007-13-08 applied to certain 
Airbus Model A318, A319, A320, and A321 series airplanes. The NPRM 
published in the Federal Register on January 6, 2017 (82 FR 1623). The 
NPRM was prompted by a determination that the unsafe condition could 
occur on additional airplanes. The NPRM proposed to continue to require 
repetitive inspections of the APU starter motor, APU inlet plenum, and 
APU air intake for discrepancies; repetitive cleaning of the APU air 
intake; and applicable corrective actions. We are issuing this AD to 
detect and correct reverse flow during APU startup, which could lead to 
flame propagation in the APU air inlet and intake duct. Such conditions 
could result in an in-flight fire in the APU area.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2016-0176, dated August 31, 2016; corrected September 1, 2016 (referred 
to after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Airbus Model 
A318, A319, A320, and A321 airplanes. The MCAI states:

    An operator reported black smoke at the rear of the fuselage 
during taxi after landing. The smoke was caused by a fire in the 
auxiliary power unit (APU) air intake. The subsequent analysis 
demonstrated that, following numerous unsuccessful APU start 
attempts in flight, there is a risk of reverse flow leading to flame 
propagation to the APU air inlet and air intake duct.
    This condition, if not detected and corrected, could result in 
an in-flight fire in the APU area.
    Prompted by these findings, Airbus issued Service Bulletin (SB) 
A320-49-1068 to provide inspection and cleaning instructions. The 
applicable Flight Crew Operating Manual (FCOM) already contained a 
limitation for the number of APU start attempts, as follows:

APU STARTER
After 3 starter motor duty cycles, wait 60 minutes before attempting 
3 more cycles

    To address this potential unsafe condition, EASA issued AD 2006-
0153 to require repetitive inspections of the APU starter motor, APU 
inlet plenum and APU air intake [for discrepancies], as well as 
repetitive cleaning of the APU air intake [and applicable corrective 
actions].
    As the reverse flow inside the APU can only occur in flight with 
the APU inlet closed, various modifications (mod) were developed to 
introduce a new electronic control box (ECB) with associated 
software, the functionality of which keeps the APU inlet door open 
for 15 minutes, following an APU auto-shutdown in flight. 
Consequently, AD 2006-0153 [which corresponds to FAA AD 2007-13-08], 
was revised reducing the Applicability by excluding certain post-mod 
aeroplanes, and introducing these modifications as optional 
terminating actions.
    After EASA AD 2006-0153R2 was issued, it was determined that, as 
an APU ECB can be replaced (or moved from one aeroplane to another) 
in service, inadvertently installing a pre-mod ECB would reintroduce 
the unsafe condition. Prompted by this finding, EASA issued AD 2016-
0159, retaining the requirements of EASA AD 2006-0153R2, which was 
superseded, expanding the Applicability and including references to 
additional optional terminating actions.
    Since EASA AD 2016-0159 was issued, it was determined that 
paragraph (5) of the [EASA] AD contained some erroneous statements, 
inadvertently excluding certain aeroplanes, those that have Airbus 
mod 23698 or mod 24498 embodied in production, from the repetitive 
actions.
    For the reason described above, this [EASA] AD retains the 
requirements of EASA AD 2016-0159, which is superseded, and corrects 
paragraph (5). For post-mod aeroplanes where, inadvertently, an 
`affected' ECB has been installed in service, this AD adds the 
requirement to restore those aeroplanes to post-mod configuration by 
installation of a `serviceable' ECB. This [EASA] AD also introduces 
some editorial changes, not affecting the required actions.
    This [EASA] AD is republished as it was determined that one 
`affected' and one `non-affected' ECB were inadvertently omitted in 
the Tables.

    Discrepancies include a defective APU starter motor, misaligned 
brush wear indicator-pin, oil contamination of the brush wear 
indicator, and dirt, debris, dust, sand, oil, combustible residues, 
grease and other contaminations of the APU inlet plenum. Corrective 
actions include replacement of the APU starter motor and cleaning the 
APU air intake, if necessary. You may examine the MCAI in the AD docket 
on the Internet at http://www.regulations.gov by searching for and 
locating Docket No. FAA-2016-9567.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM and 
the FAA's response to each comment.

Support for the NPRM

    United Airlines and Air Line Pilots Association, International, 
stated their support for the content of the NPRM.

Request To Include Missing Part Number

    Airbus asked that electronic control box (ECB) part number (P/N) 
3888394-230300 for APU GTCP36-300 be added to table 1 to paragraph (g) 
of the proposed AD. Airbus stated that the part number is missing in 
the table.
    We agree with the commenter's request. We have added ECB P/N 
3888394-230300 for APU GTCP36-300 to table 1 to paragraphs (g), (h), 
(i)(2)(ii), (j), and (k) of this AD. That part number was omitted from 
EASA AD 2016-0176, dated August 31, 2016; however, EASA issued a 
correction, which added that part number, on September 1, 2016. We have 
also included the corrected EASA AD in this final rule.

Request To Provide Retrofit Installation Method and Interchangeability 
Information

    Virgin America asked that the proposed AD requirements provide an 
approved retrofit installation method for P/N 3888394-321206. Virgin 
America also asked that the proposed AD requirements clearly state the 
interchangeability or lack of

[[Page 32624]]

interchangeability for the part numbers identified in table 2 of the 
proposed AD.
    Virgin America stated that it receives the Airbus Illustrated Parts 
Catalog (IPC) on a quarterly basis, which it regularly corrects to 
remove interchangeability. Virgin America added that in addition to 
correcting the IPC every quarter, it has repeatedly requested that 
Airbus Airworthiness and Engineering synchronize their viewpoint of how 
the IPC is intended to be utilized by operators. Virgin America noted 
that since EASA has corresponding ADs, it would mean that no ECB can be 
considered ``interchangeable'' by Airbus, since accomplishing a service 
bulletin is not the same as accomplishing an airplane maintenance 
manual. Virgin America requested this coordination within Airbus, both 
from an ever increasing manpower requirement (i.e., the more ADs, the 
more IPCs that need interchangeability monitored and removed quarterly) 
and also from a parts support request, since some parts providers use 
the IPC as the means to pool and issue parts. Virgin America concluded 
that a separate pool of non-interchangeable parts adds significantly to 
the cost impact of the proposed AD.
    We acknowledge the commenter's concerns; however, an approved 
retrofit installation method and interchangeability of part numbers are 
not addressed by this AD. While there might be merit to the commenter's 
suggestions, this AD is not the appropriate document in which to 
evaluate those suggestions. Therefore, we have not changed this AD in 
this regard.

Conclusion

    We reviewed the available data, including the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the changes described previously and minor editorial 
changes. We have determined that these changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    Airbus has issued the following service information, which 
describes procedures for replacing the ECB. These documents are 
distinct since they apply to different airplane models in different 
configurations.
     Airbus Service Bulletin A320-49-1077, Revision 04, dated 
February 27, 2013.
     Airbus Service Bulletin A320-49-1098, dated June 21, 2011.
     Airbus Service Bulletin A320-49-1102, dated January 3, 
2012.
     Airbus Service Bulletin A320-49-1107, Revision 02, dated 
May 10, 2016.
    This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section.

Costs of Compliance

    We estimate that this AD affects 1,182 airplanes of U.S. registry.
    The actions required by AD 2007-13-08, and retained in this AD, 
take about 4 work-hours per product, at an average labor rate of $85 
per work-hour. Based on these figures, the estimated cost of the 
actions that are required by AD 2007-13-08 is $340 per product.
    We also estimate that it will take about 4 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Based on these figures, we estimate the cost 
of this AD on U.S. operators to be $401,880, or $340 per product.
    We have received no definitive data that will enable us to provide 
cost estimates for the on-condition actions specified in this AD.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. ``Subtitle VII: Aviation 
Programs,'' describes in more detail the scope of the Agency's 
authority.
    We are issuing this rulemaking under the authority described in 
``Subtitle VII, Part A, Subpart III, Section 44701: General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We determined that this AD will not have federalism implications 
under Executive Order 13132. This AD will not have a substantial direct 
effect on the States, on the relationship between the national 
government and the States, or on the distribution of power and 
responsibilities among the various levels of government.
    For the reasons discussed above, I certify that this AD:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska; and
    4. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

2. The FAA amends Sec.  39.13 by removing Airworthiness Directive (AD) 
2007-13-08, Amendment 39-15112 (72 FR 33877, June 20, 2007), and adding 
the following new AD:

2017-14-11 Airbus: Amendment 39-18955; Docket No. FAA-2016-9567; 
Directorate Identifier 2016-NM-147-AD.

(a) Effective Date

    This AD is effective August 21, 2017.

(b) Affected ADs

    This AD replaces AD 2007-13-08, Amendment 39-15112 (72 FR 33877, 
June 20, 2007) (``AD 2007-13-08'').

(c) Applicability

    This AD applies to Airbus airplanes identified in paragraphs 
(c)(1), (c)(2), (c)(3), and (c)(4) of this AD, all manufacturer 
serial numbers, certificated in any category.
    (1) Model A318-111, -112, -121, and -122 airplanes.
    (2) Model A319-111, -112, -113, -114, -115, -131, -132, and -133 
airplanes.
    (3) Model A320-211, -212, -214, -231, -232, and -233 airplanes.
    (4) Model A321-111, -112, -131, -211, -212, -213, -231, and -232 
airplanes.

(d) Subject

    Air Transport Association (ATA) of America Code 49, Airborne 
Auxiliary Power.

[[Page 32625]]

(e) Reason

    This AD was prompted by a report of a fire in the auxiliary 
power unit (APU) air intake. An analysis demonstrated that, 
following numerous unsuccessful APU start attempts in flight, there 
is a risk of reverse flow, which could lead to flame propagation to 
the APU air inlet and air intake duct. This AD was also prompted by 
the determination that AD 2007-13-08 only addresses the unsafe 
condition for certain airplanes. We are issuing this AD to detect 
and correct reverse flow during APU startup, which could lead to 
flame propagation in the APU air inlet and intake duct. Such 
conditions could result in an in-flight fire in the APU area.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Repetitive Inspections and Corrective Actions

    Except as provided by paragraph (i) of this AD, within 600 
flight hours after July 25, 2007 (the effective date of AD 2007-13-
08), or within 60 days after the effective date of this AD, 
whichever occurs later: Inspect the APU starter motor, APU air inlet 
plenum, and APU air intake of each affected APU identified in table 
1 to paragraphs (g), (h), (i)(2)(ii), (j), and (k) of this AD for 
discrepancies; and do all applicable corrective actions before 
further flight; in accordance with the Accomplishment Instructions 
of Airbus Service Bulletin A320-49-1068, Revision 01, dated February 
2, 2006. Repeat the inspection thereafter at intervals not to exceed 
600 flight hours.
